Question 1

wondering if an fmri or functional imaging of the brain ever used clinically?

Accepted Answer

I suspect so...: But i cannot prove it.  It has been primarily a research tool, but where it is performed, I am sure it has been used for clinical patients.  Sorry i cannot help more.

Question 2

why is it so hard in this day and age (with functional brain imaging) for neuroscientists to finally understand a mechanism behind mental illnesses???

Accepted Answer

A lot to learn: 1) Brains are still  "smarter" than the best computers at least at some tasks. If our best tool to understand the brain is a computer, we cannot quite fully understand brains.
2) We still can't count all nerve cells, receptors and connections, so we don't know the wiring. All brain chemicals (neurotransmitters)  are still not worked out.
3) Mental illness comes from a lot of brain circuits &amp; chems

Question 3

can a pet or functional mri see level of dopamine in the brain?

Accepted Answer

NO: levels are determined by blood or urine evaluation.

Question 4

can functional neurological disorder (fnd) be linked or associated with an organic brain disease / syndrome? or even classified as that in the medical community? thanks

Accepted Answer

FND: Your question is very confusing which is probably why it hadn't been answered. Functional Neurological Disorder is really an umbrella concept for what appears to be neurologic type symptoms but with no organic or psychiatric explanation.  You could have a person who had unexplained symptoms who later was diagnosed with a known medical or psychiatric disorder.

Question 5

are there any permanent cognitive deficits/brain damage associated with being prescribed clonazepam for less than a year? and, if not, should i be just as functional cognitively and memory-wise as i was before (i.e. thered be no lasting effects)?

Accepted Answer

Wouldn't think so: Such an issue would likely have led to removal from the market decades ago (first approved in 1975). There is always a possibility you had a personal idiosyncratic reaction (rare).However, I would wonder if this is more related to whatever led them to use the drug on you to begin with.

Question 6

good afternoon doctors. if i have functional endoscopic sinus surgery for complete opacification left frontal sinus, what are the chances of blindness/eye damage and/or brain complications/damage? are there any other concerns that i should know about?

Accepted Answer

: This is a conversation to have with the Physician that is treating you, the one familiar with your unique circumstances and your personal surgical risk.

Question 7

how can you tell if your cerebrum is abnormal?

Accepted Answer

Cerebrum: I am not sure what exactly you are trying to find out as no information is provided. Cerebrum, latin  for brain, can be sick both physically and mentally but to guide you in a more specific direction, you would need to disclose more information about what's going on with the person in question.

Question 8

what is the definition or description of: cerebrum?

Accepted Answer

Most of the brain: Cerebrum essentially refers to the majority of the brain. Embryologically, it develops from the telencephalon, and together with the diencephalon, it comprises the forebrain.

Question 9

if born without cerebrum, would you be able to live?

Accepted Answer

Briefly: The residual brain parts would allow life for a day or two but death would be inevitable if such a fetus was alive at birth.  It does occur and is called anencephaly.

Question 10

what are the differences between the right and left hemispheres of the cerebrum?

Accepted Answer

Some differences: The dominant hemisphere usually determines the dominant hand, so, left hemisphere in right handers, but right hemisphere about only 40% left handedness.  Pre-dominant speech connections over dominant side, especially left again.  Yet delirium might occur from a stroke on the right side near temporal, parietal, occipital junctions.
